(KMOV) – A former St. Charles County teacher is accused of sexually assaulting a 10-year-old student he was home schooling earlier this year.

Joseph Maddock, 34, was charged with first-degree statutory sodomy.

Police said Maddock met the boy in 2012 while teaching 3rd grade at Andrews Academy in Lake St. Louis.

Authorities said around that time he convinced the 5th-grade boy’s parents to let him home school the child at his house in the 11 block of Lemans Drive.

According to court documents, Maddock taught the victim five days a week in his finished basement from Sept. 2012 to Feb. 2013.

Authorities said during several teaching sessions, Maddock would lay down on the couch and read to the student while rubbing his back and stomach.

Police said Maddock admitted to placing his hands on the child’s private area during a reading session in Jan. 2013. Authorities said Maddock confessed to the crime after the boy’s mother called police.

According to records, Maddock taught in 10 schools in the St. Louis and St. Charles areas between 2001 and 2012.

He currently works at Dynamic Pathwaysin O’Fallon, Mo., where he teaches autistic children.

News 4 tried contacting some of Maddock’s previous schools, but officials would not comment.

He remains in the St. Charles County Jail on a $50,000 cash-only bond.
